RECYCLING
Packaging equipment must be recycled. Separate all different materials (plastic, paper, cardboard,
wood…) and place them in the corresponding containers. Ensure waste collection is properly managed
with a Non-Hazardous Waste Agent.
To guarantee health and natural environmental sources protection, the European Union has
adopted the WEEE directive concerning discarded electric and electronic equipment
(SEEA).
Waste of electrical and electronic equipment (WEEE) must be collected selectively for
proper environmental management.
Our products contain electronic cards, capacitors and other electronic devices that should
be separated when they are no longer functional. These WEEEs should be managed
accordingly with a Hazardous Waste Agent.
Power Electronics promotes good environmental practices and recommends that all its
products sold outside of the European Union, once they reach the end of their life, are
separated and the WEEE managed according to the particular country applicable legislation
(especially: electronic cards, capacitors, and other electronic devices).
If you have any questions about the electric and electronic equipment waste, please contact Power
Electronics.
ELECTROMAGNETIC COMPATIBILITY (EMC)
The drive is intended to be used in industrial environment (Second Environment). It achieves compliance
with category C3 defined in IEC/EN 61800-3 standard when the installation recommendations within this
manual are followed. The driver can optionally operate in domestic environments (First Environment),
complying with category C2 defined in IEC / EN 61800-3 standard. For category C1 consult Power
Electronics. Optional IT filter.
Select communication and control system according to the drive EMC environment. Otherwise, systems
could suffer from interferences due to a low EMS level.
CAPACITORS DEPLETION
If the drive has not been operated for a long time, capacitors lose their charging characteristics and are
depleted. To prevent depletion, once a year run the device under no-load conditions during 30-60 minutes.

SAFETY INSTRUCTIONS
EN
SAFETY
•Before operating the drive, read this manual thoroughly to gain an understanding of the unit. If any
doubt exists, please contact POWER ELECTRONICS, (902 40 20 70 / [phone]) or your
nearest agent.
•Wear safety glasses when operating the drive with power applied or for when the front cover is
removed.
•Handle and transport the drive following the recommendations within this manual.
•Install the drive according to the instructions within this manual and the local regulations.
•Do not place heavy objects on the drive.
•Ensure that the drive is mounted vertically and keeping the minimum clearance distances.
•Do not drop the drive or subject it to impact.
•The SD750SP drives contain static sensitive printed circuits boards. Use anti-static safety
procedures when handling these boards.
•Avoid installing the drive in conditions that differ from those described in the Environmental Ratings
section.
CONNECTION PRECAUTIONS
•To ensure a correct operation of the drive, it is recommended to use a SCREENED CABLE for
the control wiring.
•The motor cable should comply with the requirements within this manual. Due to increased
leakage capacitance between conductors, the external ground fault protection threshold value
should be adjusted ad hoc.
•Do not disconnect motor cables if the input power supply remains connected.
•The internal circuits of the SD750SP Series will be damaged if the incoming power is connected
and applied to output terminals (U, V, W).
•Do not use power factor correction capacitors banks, surge suppressors, or RFI filters on the
output side of the drive. Doing so may damage these components.
•Always check whether the “DC Link”red LED is OFF before wiring terminals. The capacitors may
hold high-voltage even after the input power is disconnected.
•Do not connect the drive in grids whose THDv is higher than 8%.
COMMISSIONING
•Verify all parameters before operating the drive. Alteration of parameters may be required
depending on application and load.
•Always apply voltage and current signals to each terminal that are within the levels indicated in
this manual. Otherwise, damage to the drive may occur.
•For correct starting, refer to the start-up section.
HANDLING PRECAUTIONS
•When the "Automatic Restart" function is selected, observe the appropriate safety measures to
avoid any damage in case of sudden restart of the motor after an emergency and subsequent
reset.
•The "STOP / RESET" key on the driver's own keypad will be operative as long as this option has
been selected. By pressing this button, the drive will not perform an emergency stop. The driver
has a STO function which, installed with an external EMERGENCY pushbutton, will disconnect
the motor power supply and prevent the ability to generate torque in the motor.
•If an alarm is reset without having lost the reference signal (setpoint), an automatic start may
occur. Check that the system has not been configured as such. Failure to do so could result in
personal injury.
•Do not modify anything inside the driver without the supervision of Power Electronics.
•Before starting the parameter setting, reset all parameters.

SAFETY INSTRUCTIONSINTRODUCTIONINTRODUCTION
13
EARTH CONNECTION
•Ground the drive and adjoining cabinets to ensure a safe operation and to reduce electromagnetic
emission.
•Connect the input PE terminal only to the dedicated PE terminal of the drive. Do not use the case,
nor chassis screw for grounding.
•Ground the drive chassis through the labelled terminals. Use appropriate conductors to comply
with local regulations. The ground conductor should be connected first and removed last.
•Motor ground cable must be connected to the PE output terminal of the drive and not to the
installation’s ground. We recommend that the section of the ground conductor (PE) is equal or
greater than the active conductor (U, V, W).
•If the user decides to use screened motor cable, ensure a good 360° connection of the cable
screen in both the drive cabinet and the motor terminal box.

INTRODUCTION
Power Electronics has a strong commitment to reduce the levelized cost of water (LCoW) by offering
upgraded energy saving solutions. Synergies of the industrial and solar division have been exploited to
launch the high power solar pumping system SD750SP. This equipment is a customised VSD with an
increased DC range, adapted to work with AC or DC power or with a hybrid system. The SD750SP has an
updated firmware that is also capable of finding the MPP (Maximum Power Point) to maximise installation
performance.
This product allows simultaneous connection to the grid (AC) and PV field (DC). The AC input voltage
determines the DC bus voltage of the SD750SP and therefore the required DC voltage of the strings. The
maximum power produced at the set DC voltage depends on the number of PV panels connected inseries.
The SD750SP also allows self-sufficient operation by connecting itself to the PV field and generating the
energy needed to start and accelerate the pumping system. The minimum power required depends on the
hydraulic response of the complete pump load system.
The SD750SP is a compact solution that allows a quick and easy installation and commissioning. Optional
solar kits with diodes, DC protections, disconnection and filtering are available. A complete integration in
a cabinet is also available, which facilitates installation and commissioning.
